Boot Cycle
After connecting the proper cabling to the DCT6400, plug the power cord into the DCT6400 and
electrical wall outlet. Begin performing the boot cycle procedure:
After a few moments, the LED displays
HUNT
and then
FR 1
.
The DCT6400 searches for the headend out-of-band (OOB) frequency carrier. If the OOB
frequency is not set to 75.25 MHz, the LED flashes
FR 1
and then flashes
FR 2
. This
searching process repeats until the correct OOB frequency is found and the required
message for the DCT6400 model is acquired.
The LED displays and OOB frequencies are:

When multiple OOB frequencies are used, the DCT6400 pauses 40 seconds on each valid
frequency. The LED displays

and a progress indicator, which identifies a software object
download. The progress indicator, or crawling ant, moves one position around the dl display
for each segment of download received. If the
dl
stops moving up and down on the LED for
an extended period of time, contact the headend operator.
The progress indicator usually moves at a consistent rate as segment downloads are
received. If all the segments are retrieved in the first pass, the

AU
and
FP
messages are
displayed on the LED. If segments are dropped, the progress indicator appears to stall and
then inch forward after the dropped segments are retired.
